Hidden Fees in Solar Contracts: What to Watch For in 2026
Solar contracts can hide thousands of dollars in fees. Here are the 8 most common hidden costs and how to protect yourself before you sign.
Why Solar Contracts Are Complicated
Solar contracts are among the most complex consumer agreements most homeowners will ever sign. They're often 30–50 pages long, written in legal language, and signed under time pressure from a salesperson. This complexity creates opportunities for hidden fees that can cost you thousands of dollars over the life of the system.
8 Hidden Fees to Watch For
Review every solar contract for these commonly buried costs:
- Lease escalator clauses: Annual payment increases of 1–3.9% per year. Over 25 years, a 2.9% escalator nearly doubles your payment. Always calculate total payments over the full term.
- Monitoring fees: Some installers charge $5–$20/month for system monitoring. This should be included free for at least 10 years.
- Interconnection fees: Your utility may charge $100–$500 to connect your system to the grid. Confirm who pays this.
- Permit and inspection fees: Should be included in your quote. Ask explicitly — some installers add these as line items after signing.
- Removal and reinstallation fees: If you need roof repairs, some contracts charge $1,000–$3,000 to remove and reinstall panels.
- Performance guarantee penalties: Some contracts penalize you if your system underperforms, even due to factors outside your control.
- Early termination fees: Lease buyout costs can be $5,000–$20,000 if you want to exit early.
- Transfer fees: Fees to transfer a lease to a new homeowner when you sell, typically $250–$500.
How to Protect Yourself
Before signing any solar contract, take these steps:
- Get the full contract in writing before the sales appointment ends.
- Take at least 48–72 hours to review the contract. Never sign on the first visit.
- Calculate the total lease payment over the full term (not just the monthly payment).
- Ask explicitly: 'What fees are NOT included in this quote?'
- Compare quotes from at least 3 installers using EnergySage or similar platforms.
- Have a real estate attorney review the contract if you're signing a lease or PPA.
Frequently Asked Questions
What is a solar escalator clause?
An escalator clause increases your lease or PPA payment by a fixed percentage each year (typically 1–3.9%). A 2.9% annual escalator on a $150/month payment results in $290/month by year 25.
Are solar removal fees common?
Yes. Most solar leases and some loan contracts include provisions for removal and reinstallation fees if you need roof work. These fees range from $500 to $3,000 depending on the installer and system size.
